A Specification of Letters IPatent. Application led April 17, 1913,` Serial No. 761,781.

' Patented oct.21,1913.

To all whom t may concer/nl' lBe it known'that I, FRANK HALL GRANT, a citizen of Canada, resident ofthe" United Sta-tes, residing at Detroit, in the .county of Wayne and State of Michigan, have invented certain new and useful Improvements in Shingles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enablel othersA skilled in the. art to which it appertains to make and use the same'.

' This invention relates to improvements in shingles and particularly to shingles formed of asphaltum paper or similar compositions. 1 I One object of the invention is'to provide a shingle ofthis character'having its exposed end protected by a covering of'thin sheet metal which imparts to thelshingleall the advantages Vof a metal shingle ata much less cost of production. f

Another ob'ect is to protect the upper end of the shingle which underlies the crack be# v vtween shingles in the row above, by an eX- tensionrof said covering ofsheetmetal, and yet not materially increasethe cost of the same.

Another object is to produce a shingle of this character which will be strong and durable in construction, which will not rust, warp, split or leak, and which will be practically fire-proof and indestructible.-

IVith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more ifully described and claimed. j y

' In the accompanying drawings :I Figure 1 is a plan Viewr of 'a portion lof a. 'roof illust-rating the application of my improved 1 shingle; Fig. 2 is an enlarged top plan view of one of the shingles; Fig. 3 1s a bottom plan view thereof; Fig. 4 is a central longitudinal section of the shingle taken on the `line 4 4 of Fig. 2; Fig. 5 is a cross sectional View of the shingle taken on the line 5 5 of Fig. 3.

My improved shingle comprises a body l which may be of any suitable size and shape and constructed of any suitable material, the same being preferably constructed of asphaltum paper or similar composition. In the present instance the body 1 of the shingle is shown as of oblong shape and as having substantially the proportions of im ordinary shingle:` Arranged on the'outer end of the shlngle 1s` a cap plate orcovering 2 which may be formed of any suitable sheet metal,

said vcovering being preferably formed of very thin sheet copper. The cap 2 covers the 'entireouter surface of the shingle for a. distance-'somewhat 'greater than one-third the length of' the shingle and ,the inner end of the cap or covering is tapered to a point which extends upwardly for more thanhalf the .length of the shingle as shown at 3. The lower rectangular portionof the cap or covering has its sides and outer endA turned in to form ',clenching flanges 4 which engage the adjacent edges of the body of the'shingle and are 'prefer ably -pressed -into -the lower surface'of; the

shingle, so. that the outer surfaces4 of said fianges are Hush with the surface of the under side of the shingle as clearly shown in Figsl 4 and 5 Yof the drawing. Theupper taperedl end of the 'cap plate is also preferably pressed or embedded into the upper surface of the body of the shingle, so that the edges of said tapered upper end of the covering are flush with the upper surface of the body of theJ shingle. The coverings 2 of the shingles when thus constructed l are applied' to the body of the shingle under heavy pressure .which embeds the flanges v4 and upper edge of the covering into the composition forming the body of the, shingle and thereby tightly .clenches the covering in position on the shingle. The embedding ofv the flanges 4' and edge of the upper end of the. covering in the body of the shingle perfl 'mits the same tolie fiat on a roof. In lay-l ing the shingles they are. placed in courses with the shingles of one course breaking joint with those of ,the adjoiningy course in the usual manner. The shingles are fastenedV to the roof bynails or' tacks driven .i

through the'upper ends of the body of the shingle and into the sheathing boards of the roof as usual.

A shingle constructed in accordance with my invention will be' a non-conductor of heat or cold and when properly laid will f form an absolutely water tightovering for the roof which will not sweat o r rust. The metal covering of the shingles will protect the latter from hail stones and heavy storms and the body of the shingle inclosed by the covering will act to deaden the sound caused -by heavy storms or hail striking the roof.

Owing to the fact that theA coverings are constructed from very thin metal/the oost of a roof covered with my improved shingles metal roof.

will be considerably less than the usual The purpose of continuing the upper end ofthe metal coverlng into a point as shown at 3, is to causev it to underlie the crack between the shingles in the row next above so that water passing 'through this crack willv fall upon the', metal covering rather than upon the body of the shingle itself; and yet I preferably taper the upper edges of this extension to the point 3 so as yto reduce vas far as possible the amount of metal necessary for each. shingle."

. and the minor details of construction may be resorted to without departing from the prin ciple or 'sacrificing any of the 'advantages of the invention as claimed. f v

description taken in" Having thus described my inventlonwhat embedded in the lower surface of the body ofthe shingle.

2. A shingle comprising a body'7 formed of ireand water-proof material, and a metal cap overlying the lower end of said body and its sides and end,l with the upper end of said cap tapered to a point and overlying the central portion of the body, for the purpose set forth. A- ,l

In testimony whereof I have hereunto set my hand in presence oftwo subscribing'witnesses.
